Looking for an older h game

[Reapers99]

Hi everybody, I'm trying to figure out the name of an H Game that I played back in (I think, not 100% sure) 2008-2010.

 

What I can remember:

• 3d art style.
• You're a male protagonist.
• It was set in a school.
• There's one girl you have sex with.
• There are ghost girls (I think 2) that can possess the girl (and I think they change the size of her boobs.)
• I believe it was voiced (the main girl and the ghosts all had different voices (I think)).
• There was a story that unlocked more options, and there might have been a free mode as well.
• I think the gameplay was similar to AG3 and @Homemate.

 

That's the gist of what I can remember about the game. I have been trying to find this game for a bit now, scouring forums and such to no avail. If anyone could help me find this game I would be forever in your debt.
